clean out /tmp?

[Morgan Read]

Hi,
Is there a way to keeping my /tmp's cleaned out in FC?

I had what I thought was the perfect answer to keeping my /tmp's trim and in
shape by using cron scripts - but, it appears to apply to suse only?  (See
bellow.)

Regards,
Morgan.

Looks like it, yes. I use SuSE.

This is the mechanism to control a standard unix cron daemon. In turn,
the scripts in these directories (and in /etc/init.d/) read
/etc/sysconfig/cron and act on it.

This looks like it's the equivalent file for FC. If you can't find any
commments in this file relating to clearing temp directories, than I'd
conclude that FC isn't as sophisticated in this department.

The file is not personal, you can find it in the package
ftp://ftp.opensuse.org/pub/opensuse/distribution/SL-10.0-OSS-RC1/inst-source/suse/i586/aaa_base-10.0-27.i586.rpm
at /var/adm/fillup-templates/sysconfig.cron. No it would not work unless
you also installed the (parts of) the scripts which read this file.
These are
/etc/init.d/boot.cleanup
/etc/cron.daily/suse.de-clean-tmp
in the same package. You're on your own surgically implanting the
correct parts into FC.
